Abstract

Die Erfindung betrifft eine elektrothermische Anzündvorrichtung zur Anzündung einer Pulver-Treibladung (4), welche mindestens einen sich mindestens teilweise durch die Treibladung erstreckenden elektrisch leitenden Draht (11;15;19;22) umfaßt, der mit einer Stromquelle (3) verbindbar ist.
Um zu erreichen, daß die Ahzündvorrichtung einen geringen elektrischen Energiebedarf aufweist und auf einfache Weise an unterschiedliche Forderungen der Anzündvorrichtung angepaßt werden kann, schlägt die Erfindung vor, den elektrisch leitenden Draht (11;15;19;22) mit einem pyrotechnischen Anzündsatz (12;16;20) zu beschichten. Als vorteilhaft hat sich als Anzündsatz ein Gemisch auf der Basis Kaliumperchlorat-Zirkonium (KClO4-Zr) erwiesen.
